To all whom may concern:

Beit known'that I,-,OseAR BOEHM, a cltizen of the United States, residing at New York city, Manhattan, county of New York,

State of New York, have invented new and useful Improvements in Bowls or Tureens, of

which the following is a specification.

This invention relates toa covered bowl or tureen consisting essentially of two sections. viz: a lower section or bowl roper, and an upper section or lid adaptefto tightly fit upon the lower section. Both sections are preferably made of hard glass, and are rovided with double walls, between w 'ch vacuum chambers are formed. The lower section is, when desired, inclose'd within a correspondingly shaped. metal basket or casing to protect it against breaking and to providea proper support for the bowl. The joint between both sections should be such that any communication between. the interior of the vessel and the outer air is effectively prevented.

My improved covered bowl provides reliable means for preserving meals etc. in-such a manner that they retain their tem erature for a considerable length of time, ut it is obvious that the bowl may also be used for other urposes.

In t e accompanying drawing which is a vertical cross section, artly in view, through one form of a curved owl embodying my invention, the letter A indicates the bottom section or bowl proper, while the letter B designates the upper section or lid. Bowl A comprises an inner curved wall 1, and an outer curved wall 2, the shape of which corres onds, substantially, to that of wall 1.

alls 1 and2, being connected along their upper rim as at 3, are preferably made of a.

single piece of glass, and their sizes are such that a comparatively narrow chamber 4 is formed between them. Wall 1 as well as Wall 2 is shown to be so bulged or curved that its cross section forms a figure slightly larger than a half-ellipse, or in other words, the upper rim of section A is drawn inward to form a contracted neck, although said section may be of any other convenient shape, without de arting from the spirit of my invention.

' id B comprises an inner curved wall 5, and an outer curved. wall 6, which are so spaced that a narrow chamber 7 is formed between them. Walls 5 and 6 are connected along their lower rim as at 8, and are also preferably made of a single piece of glass.

' Rim 8 is b'eveled'to engage a corresponding bevel 9' of edge 3, and thereby form a tight joint. At its apex, wall 6 is bulged outward to form a vacuum insulated handle or knob 10. It is obvious that the cooperating edges 3 and 8 of sections A and, B may be of any other-she or construction in order to produce the esired joint, as long as they answer the urpose of preventing any communication etween the interior of the bowl and the outer air.

14 is reinforced by a ring 15, which simultaneously forms a guard for the lower edge of lid B,.when placin the latter upon bowl A. Basket 14 is slight y drawn or spun inward at its u per edge, to correspond to the shape of the owl, so that a disengagement of t e latter from the basket is prevented. At its bottom, basket 14 has a downwardly extendw ing rim 16, constituting the foot of the basket. It is obvious that the shape of the supporting basket 14, and the means foreccurely holding the same to pan A may be varied, without departing from the spirit of my invention.

It will be seen, that by the construction described, a covered bowl or tureen is provided the interior of which is readily accessible for introducing and takingout the meals or other contents thereof, and also for cleaning purposes. When the bowl is roperly closed by placing the vacuum insu ated lid upon the lower section, the contentsof the bowl will retain their temperature for a considerable length of time. 1

I claim: v

1. As a new article of manufacture, a vacuum insulated bowl, a vacuum insulated lid ada ted to be seated upon the bowl, a metal asket snuglyembracing the bowl, means for securely holding thebasket to the bowl, and a foot formed on said basket.

2. As a new article of manufacture, a vacuum insulated bowl having a contracted upper edge, a vacuum insulated lid ada ted e seated upon the bowl-edge, a metal as ket snugly embracing the bowl and havin a reinforcing rim arranged slightly below 51c bowl'edge, said rim constituting a uard for the lid, and a foot formed on the has et.

3. As a new article of manufacture, a glass bowl comprising an inner wall and an outer wall having a vacuum space therebetween, a glass lid removably en agin the bowl and comprising an inner wal an an outer wall having a vacuum space therebetween, and an outwardly extending bulge formed on the outer lid-wall, said bulge constituting a vacuum insulated handle.

4; As a new article of manufacture. a glass seams therebetween, an outwardly extending silver lined bulge formed at the a ex of the outer lid wall, said bulge constituting a vacuum insulated handle, and means for providing a tight joint between bowl and lid.
